A mother’s quest to cure her son

Researchers have discovered a link between circadian rhythms and Angelman syndrome, a genetic disorder which inhibits brain development leaving its victims unable to speak while suffering from seizures and sleep problems. The link between the biological clock and Angelman's could prove to be a powerful tool in the search for treatments and a possible cure for the disease. Its discovery was made in part by a mother who has sacrificed everything in order to try and help her son. Ben Gruber reports.

INTRO: Researchers have discovered a link between circadian rhythms and Angelman syndrome, a genetic disorder which inhibits brain development leaving its victims unable to speak while suffering from seizures and sleep problems. The link between the biological clock and Angelman's could prove to be a powerful tool in the search for treatments and a possible cure for the disease. Its discovery was made in part by a mother who has sacrificed everything in order to try and help her son. Ben Gruber has more.
STORY: At 55-years-old, Terry Jo Bichell is a couple of months away from earning a PHD in neuroscience. She says it puts her one step closer to achieving a goal she set out for herself 16 years ago - to cure her son Louis from a debilitating genetic disorder.
A mother of five, Terry Jo had spent her life dedicated to helping woman and children, first as a documentary film maker in Africa and then as a nurse and midwife.
(SOUNDBITE) (English) TERRY JO BICHELL, NEUROSCIENCE PHD CANDIDATE, MOTHER OF LOUIS BICHELL, SAYING:
"When I had my fifth kid and he turned out to be diagnosed with Angelman Syndrome I stopped caring about other woman children and other woman's problems and that is really true.
Terry Jo shifted her entire focus to Louis.
Angelman Syndrome, or AS, is a neuro-genetic disorder characterized by intellectual and developmental disabilities. It occurs when the maternal gene, UBE3A, is either missing or damaged. That gene regulates the concentration of a protein important to development in the brain.
For more than a decade, Terry Jo sought out researchers and helped fund experiments and clinical trials in the hopes of finding treatments for AS. Over time, she came to the realization that in order to really make a difference in the world of doctors and scientists, she needed to become one herself.
During that time, research towards experimental treatments for AS progressed, revolving around ways to activate the paternal copy of UBE3A in the brain. The experiments proved promising in mouse models. The problem is that even if a drug is successful in activating the paternal gene, the researchers had no viable way to gauge if it is actually working as changes could take months or years to manifest. They needed a litmus test of sorts.
Terry Jo found one.
As part of her studies, she started working with Carl Johnson, a professor of biological sciences at Vanderbilt University. They discovered a link between AS and circadian rhythms with mice models showing that the disorder effects the biological clock.
(SOUNDBITE) (English) CARL JOHNSON, PROFESSOR OF BIOLOGICAL SCIENCES, SAYING:
"Our piece of the puzzle could be to use this biological clock phenomenon to see if the therapeutic treatment changes the biological clock which would suggest that, yes, that treatment is really working."
Terry Jo feels her life has gone full circle, back to the days of helping others.
(SOUNDBITE) (English) TERRY JO BICHELL, NEUROSCIENCE PHD CANDIDATE, MOTHER OF LOUIS BICHELL, SAYING:
"So all of this has been a push to cure my kid and then in the end, I am going to cure other woman's kids and you know what? And that is so great. I met this baby just a couple of months ago. I was looking at that baby and I was thinking, we are going to cure that baby, we are going to cure that baby."
Terry Jo says she will not rest until that day comes.
